A CMOS Dual Bus Memory Board from Dynapath Systems, part number 501-03883-00, with secondary board reference 502-03093 visible on the PCB silkscreen. Dated to the 42nd week of 1984, this is a Bendix-era ISA-format board used in Dynapath Delta series CNC control systems. The board carries serial number D09417 and board assembly number 503, as visible on the PCB edge label. The memory array is populated with Fujitsu MB8416A-15L CMOS SRAM ICs across multiple rows, with the board silkscreen indicating a 5V VCCA supply rail. Edge connectors are gold-plated, consistent with the ISA bus interface standard used in Dynapath Delta control rack assemblies. Write protect functionality is indicated by an on-board switch labeled "ON WRITE PROTECT OFF." Additional sub-board stickers reference part numbers 502-70144-00, 502-70146-00, and 502-70145-00. This board provides program and parameter storage within a Dynapath Delta CNC control rack and is directly relevant to owners of legacy Dynapath or Bendix-branded machining centers that utilize the original 503-series ISA card rack architecture.
